Plane with no stall warning device?
Researching a question from a club member, I read in the FAR's:
§**23.207 *Stall warning. [...] (b) The stall warning may be furnished either through the inherent aerodynamic qualities of the airplane or by a device that will give clearly distinguishable indications under expected conditions of flight. Every plane I've ever flown has a mechanical stall warning device (some visual, some aural), but apparantly it's possible to certify a plane without one. Does anybody know of any real life examples of planes certified without stall warning devices? |

Does anybody know of any real life examples of planes certified without stall warning devices? Roy, I own a Piper Pacer (PA22/20, Tripacer converted to Tailwheel configuration) It was originally built by Piper in 1958 (fairly late model as TriPacers go). It has no stall warning vane/switch/horn/light, and never had one. None of the PA12/14/20/22 series do. Dunno about PA18. This one has STCed add-on very droopy wingtips (inverted winglet). The stall is very benign. Prestall indication is a slight buffet, followed by the nose dropping (assuming you keep the yoke full back, i.e. you are not proactively helping it recover), followed by self recovery as a slight dive, followed by the nose going back up again for another mini-stall... Sort of a "nodding" motion. btw- the stall occurs at an indicated airspeed of ~45mph... MikeM PA22/20 Pacer '00Z see http://home.utah.edu/~mgm17160/Island/flying.jpg |

Planes I've flown without stall warning devices: Bellanca 7ECA Citabria Piper J3 Cub Piper PA11 Cub Piper PA12 Super Cruiser Piper PA18 Super Cub Many older aircraft do not have them, heck, the stall horn in a C172 startled me for a second after flying rag wing Pipers for a few hundred hours... -- Mike |

Add my Taylorcraft BC12D. But most of these were CAA.

I honestly don't remember if it had a stall warning or not. My recollection is you knew you were stalled when you saw the ground going round-and-round :-) |

Does anybody know of any real life examples of planes certified without stall warning devices? My Johnson Rocket has no stall warning devise, nor stall strips, yet it gives a nice, straight-ahead stall, with plenty of warning, and was a real hot rod by 1946 standards. |

wrote: The SOCATA Rallye does NOT have a stall warning device! It has automatic leading edge slats which will pop out at larger angels of attack, but you are still well above stall. A power off stall is very interesting in this aircraft. You start to get stall buffett and, if you simply hold the yoke all the way back, you descend a little over 1000 fpm with the nose level on the horizon. You can turn with just the ailerons as you are descending. What happens if you yank the sitck back? Or if you start to apply rudder to accelerate a turn and then apply opposite aileron to keep from banking too steeply and just keep on crossing the controls while you bleed off airspeed? Just curious. I'm sure the results in the Socata are benign. Don |
